Abstract

The invention belongs to the technical field of thermoplastic composite materials, and particularly relates to a multifunctional thermoplastic composite material plate. The composite material plate is composed of an isolation layer, a functional surface layer, a buffer layer, a reinforcing layer and a dielectric layer, all the layers are compounded through hot pressing to form the composite material plate, the buffer layer is embedded into the functional surface layer and the reinforcing layer, and the dielectric layer is partially embedded into the reinforcing layer. The lower surface of the isolation layer is attached to the upper surface of the functional surface layer and is provided with a strippable interface; the lower surface of the functional surface layer and the upper surface of the enhancement layer have no obvious interface and cannot be peeled off. The multifunctional thermoplastic composite material plate not only has excellent mechanical properties, but also has aging resistance, antibacterial and mildew-proof properties and scratch resistance; the surface is attractive; the adhesive tape can be combined and connected with various materials in manners of gluing, hot welding and the like, and has higher peel strength; and secondary forming process is easy.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic composite materials. More specifically, it relates to a multifunctional thermoplastic composite panel. Background technique [0002] Fiber-reinforced thermoplastic composites have been widely used in rail transit, aerospace and construction due to their characteristics of light weight, high strength, secondary molding, and recycling. However, they are limited by mass manufacturing technology and cost constraints, and cannot balance Issues such as special functional requirements in various application fields are greatly limiting its application market and high-speed growth momentum. Therefore, developing in a multi-functional direction is an inevitable trend to take advantage of composite materials. [0003] Patent CN 107571577A discloses a composite material plate, which also includes an upper adhesive layer and a lower adhesive layer bonded to the upper and lower surfaces of the composite ...
